green, social & sustainability bonds

What are green and social bonds?

Green, social and sustainability bonds are no different than traditional bonds in terms of their structure and sale, but labeled bonds may only be used for eligible activities. They offer additional elements of transparency and often include an external review which attests to the environmental and/or social benefits of the funded activities, and conformance with ICMA’s Principles or CBI’s Climate Bonds Standard.

What can green bonds be used for?

Bonds that finance activities in the following sectors may be eligible for green bonds designation:

  • Water Infrastructure
  • Renewable Energy
  • Low Carbon Buildings
  • Energy Efficiency
  • Electrification
  • Transportation
  • Pollution Prevention and Control
  • Biofuels
  • Agriculture and Forestry
  • Fisheries
  • Climate Change Adaptation or Mitigation
  • Green Products and Technologies

Why do public agencies choose green, social or sustainability bonds?

Public agencies have many motivations for using green, social or sustainability bonds.

  • Bring more investors to the table. Labeled bonds attract investors who are focused on sustainability attributes.
  • Communicate goals and directives related to sustainability or social equity and explain how these are advanced with bond-financed activities.
  • Increase transparency and accountability to the public, investors, and ratings agencies about the important work your organization is doing.
  • Green and social bonds are in high demand, are often over-subscribed, and may trade better in the secondary market.

How are green, social and sustainability bonds different than traditional bonds?

Green, social and sustainability bonds are no different than traditional bonds in terms of their structure and sale, but labeled bonds may only be used for eligible activities. They offer additional elements of transparency and often include an independent external review which attests to the environmental and/or social benefits of the funded activities, and conformance with various standards.

What is a sustainability bond?

A sustainability bond finances or refinances activities that provide both environmental and social benefits. The ICMA’s Sustainability Bond Guidelines outline the criteria and intention for the sustainability bond label.

What can social bonds be used for?

The focus of a social bond should be on providing a benefit to a target population, which in some cases can be defined as the general public. Eligible activities in these sectors often qualify:

  • Affordable Housing
  • Education
  • Healthcare
  • Food Security
  • Essential Services
  • Others

Isn’t every municipal bond green or social?

No. While municipal bonds are generally focused on providing a public benefit, not every muni bond has a clear environmental or social benefit, or meets the ICMA standards. Bonds often have mixed uses of proceeds. Not all activities are green. Investors, wary of “greenwashing” or “impact washing,” look for a qualified Second Party Opinion to provide additional assurance.

What types of financing can be labeled as green, social or sustainability bonds?

  • Use of Proceeds Bonds
  • Use of Proceeds Revenue Bonds
  • Project Bonds
  • Securitized Bonds
  • Other Debt Instruments
  • Refunding Bonds
  • Bond Anticipation Notes
  • Private Placements
  • Environmental or Social Impact Bonds
  • Loans
  • Sovereign Debt
  • Bonds Sukuk

external reviews

How a Second Party Opinion Increases Transparency

The purpose of a Second Party Opinion is to clearly identify and sometimes quantify the environmental or social benefits of the bond-financed activities, in order to give investors a higher degree of confidence that these benefits are in fact real. The external review also confirms that the bond conforms with internationally accepted standards. “Greenwashing” or “social washing” occurs when environmental or social benefits are claimed inappropriately.

Sustainability attributes often have the added benefit of mitigating certain risks. Where appropriate, Kestrel includes discussion of resilience features and risk mitigants in the Second Party Opinion. Second Party Opinions from Kestrel include benchmarking with Kestrel Sustainability Intelligence.

With our deep background in consulting to state and local governments, and diverse experience with infrastructure and capital projects, the Kestrel team adds value on every transaction.

How long does a Second Party Opinion take?

Kestrel can deliver Second Party Opinions in a matter of days when transactions require an accelerated timeline. Many engagements are planned over several weeks to allow time for discussions and internal review by financing teams and counsel. However, the analytical work itself can be completed quickly.

Why designate green/social/sustainability bonds?

  • Increase Demand. Labelled bonds can attract new investors with various investment strategies such as Green Bond funds, Transition Risk, or Impact Investing.
  • Diversify Investors. Expand the pool of potential buyers beyond the traditional municipal bond investors. Many EU asset owners have sustainable investing mandates. Green Bonds are considered sustainable investments, and Second Party Opinions facilitate compliance. Asset managers can buy these and comply with sustainable investing mandates.
  • Enhance Transparency.  Second Party Opinions and Sustainability& Resilience Profiles give an additional layer of information for investors, including how the bond-financed activities advance climate action goals and plans, or improve resilience to physical risks.
  • Enhance Liquidity through Green Bond Indexes. Green bonds >$300M with certain characteristics are eligible for listing in various indexes. Indexes enhance liquidity because they bring the bonds to the attention of a broader range of investors, especially those tracking or benchmarking their portfolios to that index. Indexes often include diverse investors. The addition of a US green bond facilitates access to a wider pool of potential buyers and sellers, increasing trading volume. Active traders and arbitrageurs who follow index movements may capitalize on demand shifts when the bond is added to the index.
  • Enhance Reputation and Showcase Leadership. Issuers can signal sustainability commitments to their stakeholders and demonstrate leadership in decarbonizing and resilient infrastructure. Green bonds can drive progress toward multiple objectives. Thousands of mayors, governors, tribal leaders, college presidents, faith leaders, health care executives, and others have pledged support for sustainability.

Benefits of using green and social bonds can also be seen within the organization, as the process can facilitate alignment of internal social and/or environmental directives. As part of evaluating how a bond aligns with the entity’s mission or purpose, there can be renewed focus within the organization on expanding positive impacts.

Pricing Premium

Researchers from Wharton have found clear evidence of investors paying more for bonds that have verified infrastructure information in the form of Kestrel Sustainability Scores, regardless of green or social designations. Read a summary of the research from Wharton.

Demand for green, social, and sustainability bonds with independent, external reviews is increasing and in some cases has resulted in a pricing premium. The Climate Bonds Initiative 2023 Green Bond Pricing Report described tighter spreads and more oversubscription on green bonds versus non-green counterparts.

reporting

What reporting is required?

Post-issuance reporting is typically included in our engagement. We also encourage issuers to report meaningful metrics and make it easy for investors to find this information.  Issuers in some sectors such as healthcare or affordable housing already report on the bond-financed activities, so it is just a matter of making that information easier for investors to find.

The full benefit of a green or social bond may not be realized unless an issuer plans to tell investors what was achieved. Certain investors consider the availability of impact information in making their decisions to buy.
